Secondary SIP Server Configures the URL or IP address, and port of the SIP server. This

will be used when the primary SIP server fails.

SIP User ID

Configures the user account information, provided by your VoIP

service provider (ITSP). It is usually in the form of digits similar to

phone number or actually a phone number.

SIP Authentication ID Configures the SIP service subscriber’s ID used for authentication.

It can be identical to or different from the SIP User ID.

purpose.

Display Name Configures the SIP server subscriber’s name (optional) that will be

used for Caller ID display.

Tel URI

Indicates E.164 number in “From” header by adding “User=Phone”

parameter or

using “Tel:” in SIP packets if the base has an assigned PSTN

Number.

●Disabled: Will use “SIP User ID” information in the Request-

Line and “From” header.

●User=Phone: “User=Phone” parameter will be attached to the

Request-Line and “From” header in the SIP request to indicate

the E.164 number. If set to "Enable".

●Enabled: "Tel:" will be used instead of "sip:" in the SIP request.

Please consult your carrier before changing this parameter. Default

is Disabled.

Voice Mail Access Number Defines the voice mail portal access number to allow users

accessing their voice messages.

Network Settings

Outbound Proxy

Configures the IP address or Domain name of the Primary

Outbound Proxy, Media Gateway, or Session Border Controller. It is

used by the phone for Firewall or NAT penetration in different

network environments. If a symmetric NAT is detected, STUN will

not work and ONLY an Outbound Proxy can provide a solution.

Secondary Outbound Proxy

Configures the IP address or Domain name of the Secondary

Outbound Proxy, Media Gateway, or Session Border Controller.

Secondary outbound proxy will be used when the primary outbound

proxy fails.

DNS Mode

Selects DNS mode to use for the client to look up server. One mode

can be chosen.

●A Record: resolves IP Address of target according to domain

name.

●SRV: DNS SRV resource records indicate how to find services

for various

3. protocols.

●NAPTR/SRV: Naming Authority Pointer according to RFC

2915.

Default is A Record.

DNS SRV Fail-over Mode

The option will decide which IP is going to be used in sending

subsequent SIP packets (ex: Register refresh requests) after the list

of IPs for SIP server host is resolved with DNS SRV.

●Default (prefer server with lowest SRV priority): The phone

will always prefer to send SIP requests to the available server

having the lowest priority, and in case it is down it contacts the

next one, but once the server having lowest priority is UP again,

the phone will switch over to this one.

●Saved one until DNS TTL (Stay on responding IP until DNS

timeout): On this mode, the phone will resolve DNS SRV

records and tries to send the request to the server having lowest

priority and if it does not respond, it will move on to the next IP

until one of the servers responds, once this happen the phone

will keep contacting this responding IP until DNS timeout (30

minutes) before starting over.

●Saved one until no response (Stay on responding IP until its

failure): On this mode, the phone will send SIP requests to the

last responding IP, and it does not failover/switchover to the

next one until this responding server is down.

Note: WP820 now supports failover and redundancy requests

coming from Cisco/BW systems.

NAT Traversal Specifies which NAT traversal mechanism will be enabled on the

phone. It can be selected from the dropdown list:

●NAT NO

●STUN

●Keep-alive

●Auto

●OpenVPN

If the outbound proxy is configured and used, it can be set to “NAT

NO”.

If set to "STUN" and STUN server is configured, the phone will

periodically send STUN message to the SUTN server to get the

Table 12: Account/General Settings

Account/SIP Settings

public IP address of its NAT environment and keep the NAT port

open. STUN will not work if the NAT is symmetric type.

If set to “Keep-alive”, the phone will send the STUN packets to

maintain the connection that is first established during registration

of the phone. The “Keep-alive” packets will fool the NAT device

into keeping the connection open and this allows the host server to

send SIP requests directly to the registered phone.

If it needs to use OpenVPN to connect host server, it needs to set it

to “OpenVPN”. The default setting is "NAT NO".

Proxy-Require

Adds the Proxy-Required header in the SIP message. It is used to

indicate proxy-sensitive features that must be supported by the

proxy. Do not configure this parameter unless this feature is

supported on the SIP server.

SIP Basic Settings

SIP

Registration

Allows the phone to send SIP REGISTER messages to the proxy/server.

The default setting is "Yes".

Unregister

before New

Registration

Controls whether to clear SIP user’s information by sending un-register request to the proxy server. When set to "All", the

un-registration is performed by sending a REGISTER message with “Contact” header set to * and Expires=0 parameters

to the SIP server when the phone starts pre-registration after rebooting. If set to "Instance", the phone only cleans the

current SIP user's info by sending REGISTER message with “Contact” header set to concerned SIP user’s info and

Expires=0 parameters to the SIP server. The default setting is "Instance".

Register

Expiration

(m)

Configures the time period (in minutes) in which the phone refreshes its registration with the specified registrar. The

default setting is 60. The maximum value is 64800 (about 45 days).

Subscribe

Expiration

(m)

Specifies the frequency (in minutes) in which the phone refreshes its subscription with the specified register. The

maximum value is 64800(about 45 days).

Re-register

Expiration

(s)

Specifies the time frequency (in seconds) that the phone sends re-registration request before the Register Expiration. The

default setting is 0. The range is from 0 to 64800.

Registration

Retry Wait

Time (s)

Configures the time period (in seconds) in which the phone will retry the registration process in the event that is failed.

The default setting is 20. The maximum value is 3600 (1 hour).

Add Auth

Header On

RE-

REGISTER

Configure if the SIP account needs to add Auth header in RE-REGISTER.

●If the option is checked, device will always add authentication header in REGISTER.

●If the option is unchecked, device will only send authentication for the first REGISTER.

Enable SIP

OPTIONS

Keep Alive

Enables SIP OPTIONS to track account registration status so the phone will send periodic OPTIONS message to server to

track the connection status with the server. The default setting is "No".

SIP

OPTIONS

Configures the time interval when the phone sends OPTIONS message to SIP server. The default setting is 30 seconds,

which means the phone will send an OPTIONS message to the server every 30 seconds. The valid range is 1-64800.

Keep Alive

Interval (s)

SIP

OPTIONS

Keep Alive

Maximum

Tries

Configures the maximum times of sending OPTIONS message consistently from the phone to server. Phone will keep

sending OPTIONS messages until it receives response from SIP server. The default setting is "3", which means when the

phone sends OPTIONS message for 3 times, and SIP server does not respond this message, the phone will send RE-

REGISTER message to register again. The valid range is 3-10.

Subscribe

for MWI

Configures the phone to subscribe voice message service. If it is set to "Yes", the phone will periodically send SIP

SUBSCRIBE message for Message Waiting Indication service. WP820 phone supports both synchronized and non-

synchronized MWI. The default setting is "No".

Use Privacy

Header

Determines if the Privacy header will be presented in the SIP INVITE message and if it includes the caller info in this

header. If it is set to "Default", the Privacy Header will be omitted in INVITE when "Huawei IMS" special feature is

active. If set to "Yes", it will always be presented. If set to "No", it will always be omitted. The default setting is "Default".
